The 100 x 100 OASR horn also arrived, It has a 25mm throat with a screw on mount The retail price was $57 USD. I don't have any screw on drivers so I will have to find an adapter.

I think the OASR horn is the more interesting of the two visually. The low price of $57 should make all the 4430 diy people very happy.

Hey Tom, did you get a chance to do any testing with these waveguides? I am particularly interested in trying out the pt-f1010hf with my 2450SL drivers. I think I read in JBL's description of this wavequide that they were testing it with the 2451, which is almost identical to my drivers, except for the bolt pattern. Anyway, please let us know what your impressions are. Thanks!
